Mapper, modder, and 3d artist here. With the big update to Portal 2 it's really allowed for people like me and I'm sure many others to drive head first into creating awesome content.

The problem now is who do we have test said content with? Because I've found it very difficult despite how easy Steam Workshop is to use. I imagine the 40,000+ maps already uploaded adds a little to that challenge.

So here's my idea. Create a group open to everyone. Anyone who wants to get together, discuss, test, and provide constructive feed back to others are invited. From novice mappers to Source SDK professionals. All are welcome.
